Build A Bug

I am learning to use standard place value to solve multiplication problems. The easy thing for me was answering timetables, additions, subtractions, multiplications and division questions. It was easy because I know the strategies to mathematics problems.  Answering the questions were very challenging, it was really fast was really difficult for me. If I asked my teacher, if she can give me difficult questions, I can challenge myself and I can improve my work. The thing I need to learn next is to add mixed fractions and to know more fraction sums.
